How to Secure a Wobbly Toilet with Shims · Step 4 of 5
In this video
If the toilet still wobbles, identify the gaps between the toilet base and the floor. Firmly push shims into these gaps until the toilet is completely stable and does not rock. The video uses cedar wood shims, but plastic shims are also an excellent, water-resistant choice. Once the toilet is stable, use a utility knife to carefully score the shims flush with the toilet base and snap off the excess portion.
Goal: Level and stabilize the toilet base.
- Place shims on multiple sides if necessary to ensure the toilet is level and stable in all directions.

FAQs
How do I know if my wobbly toilet needs shims or a more serious repair?
Shims are ideal for minor rocking caused by uneven flooring or a slight gap at the base. If the wobbling is significant, accompanied by leaks, or if the toilet moves freely from the floor, you might have loose flange bolts, a damaged wax ring, or a compromised subfloor, which requires more extensive repair than just shims.
Is this project truly 'beginner' level, and can it realistically be completed in 2 hours?
Yes, securing a wobbly toilet with shims is a beginner-friendly DIY task. Most of the time is spent diagnosing, inserting shims, and applying caulk. With the recommended tools and materials, a novice can typically complete it within the estimated 2 hours, assuming no unexpected issues like a broken flange.
Do I need to buy all the specific tools listed, or are there acceptable alternatives?
While the listed tools like a utility knife and adjustable wrench are highly recommended for efficiency and safety, some generic equivalents can work. For example, a basic screwdriver set can replace the specialized flathead, and any sharp utility knife will trim shims. However, a good caulk gun is essential for a clean, professional finish.
What are the most common mistakes to avoid when shimming a toilet, and how do I prevent them?
A common mistake is overtightening closet bolts, which can crack the toilet base. Another is not checking all sides for gaps, leading to uneven shimming. Prevent this by gently hand-tightening bolts first, then incrementally shimming around the entire base until the toilet is stable, ensuring even contact.
